Verify Your Microsoft Account License

Open your web browser and go to account.microsoft.com/services.
Sign in using the exact Microsoft account originally used to redeem your Office 2019 purchase.
Look under the 'Services & subscriptions' section to confirm that the Office 2019 Home & Business license is listed and active.

Fix Software Protection Platform Registry Permissions
Adjust registry permissions for the NETWORK SERVICE account if licensing data is blocked.

- 1. Download WPS Office: Visit the official WPS website and download the free installer.

Frequently Asked Questions
Why does my Office 2019 show as unlicensed when I bought it?
This can happen due to credential conflicts, expired cached tokens, or Windows registry permission issues that block the Software Protection service from reading your valid license.
Will reinstalling Office 2019 fix the unlicensed product error?
Reinstalling can help if core application files are corrupted. However, if the issue is tied to registry permissions or Microsoft account syncing problems, a reinstall alone will not resolve the unlicensed status.
How do I know if I have a subscription or a standalone license?
Log in to account.microsoft.com/services. Office 2019 Home & Business will appear as a standalone, one-time purchase, whereas Microsoft 365 will show up as an active subscription with a recurring billing or expiration date.
What is the NETWORK SERVICE account in the Windows registry?
It is a built-in Windows account that securely manages various system services. The Software Protection Platform requires this account to have 'Full control' permissions to verify your Office license correctly.
